We divide 816840 by 78
We want to divide 816840 by 78.

Advancing to step 1:
8 divided by 78 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 78

On to step 2:
78 can be fit into 81 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 78 from 81.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 78

On to step 3:
78 goes into 36 0 times with a remainder of 36.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 36, we end up with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 78

Going ahead to step 4:
78 goes into 368 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 312 from 368 to get 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 78

Let's proceed to step 5:
564 divided by 78 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 1047.0
If we take 546 away from 564, we end up with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 78

Going ahead to step 6:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 10472.0
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
If we divide 240 by 78, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 10472.3
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
78 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10472.3
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
600 divided by 78 is 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 10472.307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
If we divide 540 by 78, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 10472.3076
Subtract 468 from 540 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
When dividing 720 by 78, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 10472.30769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 10472.307692
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
78 goes into 240 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 10472.3076923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
60 divided by 78 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10472.3076923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 10472.3076923, and the remainder is 6e-08.
